FLASH BOOTLOAD -- Loads new modem software from a flash device
This feature allows you to upgrade your modem software from a file placed onto the thumb frive. All you
need to do is place a file containing the latest version of the modem software onto your thumb drive, as
downloaded from the NUE-PSK website. This hex file may then be easily programmed into the processor
of your modem. Thus, you no longer need to use a serial adapter to upgrade your modem software!
NOTE:
This Flash Bootload feature has no real value right now because it only has the ability to
reprogram your modem with the very same software as what you are running after doing the required
conventional upgrade to v1.33c
. That is, you end up with exactly what you start out with ... v1.33c.
However if you really wish to try out the feature, you could follow these steps ...
1)
Download the modem software
mem1_34f_img.zip
to your computer and unzip it to form the file
called
mem.dat
, and then copy the
mem.dat
file to your thumb drive.
2)
Insert the thumb drive into the modem and select the Flash Bootload function in the modem menu
underneath the Select pushbutton. (Hold the Select pushbutton down for more than 1/2 second and turn
the dial counterclockwise until Flash Bootload is displayed.)
3)
Press the Select pushbutton and see "Abort" displayed beneath Flash Bootload. Turn the dial one
notch to see "Start Bootload" displayed.
4)
Ensuring that your thumb drive is inserted,
TAP
the Select pushbutton and in about 15 seconds your
modem will reboot and start up the software version you just loaded.

PC BOOTLOAD -- Loads new modem software from a flash device
This feature allows you to load a new version of a software hex file onto your modem from your PC, much
in the same way as you did previously when using a serial adapter.
NOTE:
This PC Bootload feature also has no real value right now because it only has the ability to
reprogram your modem with the very same software as what you are running after doing the required
conventional upgrade to v1.34f. That is, you end up with exactly what you start out with ... v1.34f.
However if you really wish to try out the feature, you could follow these steps ...
1)
Download the modem software
modem1_34fFP.hex
to your computer, and then connect your modem
to the USB port on your PC. You will use a suitable cable that plugs into the square USB jack on the
modem and into the rectangular USB jack on the PC. When you plug in both ends of the cable, the
computer will recognize the USB port
2)
Ready your PC (in the same fashion as done previously when using the separate serial adapter) by
bringing up a Command Prompt window on the PC, navigating to the location where the PROG program
and your modem software hex file reside (the root of the C: drive is convenient), and type:
prog -i com5 modem1_34fFP.hex
where the COM port number is that used by your PC for the USB ports. Do not hit <Enter> yet until you
have readied the modem side of the connection.
